PHILIP DIEHILAND MARTIN `HEMLEB, OF ELIZABETH, NEW JERSEY, AS- SIGNORS TO THE SINGER MANUFACTURING COMPANY, OF NEW JERSEY.

RUFFLING SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 656,441, dated August 21, 1900.`

Application iiled June 26,1899. Serial No. 721,919. (No model.) v

To all whom it may arm/cern:

Be it known that We, PHILIP DIEHL and MARTIN HEMLEB,citizens of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have inventedcertain new and useful Improvement-s in Sewing-Machine Rufflers or Gatherers, of which the following is a specilieation, reference being had therein to the accompanying drawings.

This invention has for its object to provide a sewing-machine rnfiiing or gathering device which is adapted to be thrown out of action by the attendant while the machine is running, so that the machine may do plain stitching or may form stitched rui'ies or gathers,

as may be desired,without requiring the rapid operation of the machine to be suspended. Thus in doing such work as sewing sleeves into shirts, where it is desired to gather the fabric during a portion of the seam and to form a portion of the seam plain, the attendant may at any desired moment throw the ruifier or gatherer into or out of operation Without stopping the machine, this being preferably effected by a treadle or knee-lever-operated device actuated from beneath the work-plate, thus leaving the hands of the attendant free for the convenient manipulation of the work.

In the accompanying drawings, Figure lis a rear side viewof one style of Singer sewing-machine with the invention applied thereto. Fig. 2 is a partial plan View of the same. Fig. 3 is a sectional elevation on line 3 3 Fig. 2 looking in the direction of the arrows adjacent to said line. Fig. 4 is a front end elevation of the machine-head with the faceplate removed, and Fig. 5 is a front side elevation of the same. Fig. Gis a detail view of part of the coupling and uncoupling mechanlsm.

A denotes the head at the forward end of the machine bracket-arm A.

Bis the needlebar,operated in a well-known manner from a crank b on the driving-shaft h through a pitman b2.

C is a bracket attached to the head A, and to which bracket is pivoted at c an operatinglever c', connected by a link c2 with an elbowlever c3, carrying the rufiiing or plaiting blade t will be forced into said notch, thus coupling c4. The link c2 has an adj ustable connection at is upper end with the operating-leverc' by means of the curved groove c5 in one arm M of said lever, the latter being forked at cl at its other end for engagement with a stud d on a vertically-reciprocating operating-bar D, which imparts movement to the said lever c'.

The driving-shaft b' is provided at the rear of the crank h with an eccentric b3, embraced 6o by a forked arm e on a rock-shaft e, having its bearing in a bracket E, attached to the rear side of the head A, said shaft having a second arm e2, carrying at its forward end a sliding coupling-pin e3, adapted toengage a notch ol' in the operating-bar D.

Loosely mounted on'the shaft e is a lever f, having an incline f', with which the rear end of a small rod f3, iitted to slide loosely in the bracket E, is in contact, said rod being pressed toward the incline on said lever by a spring e4 on the `arm e2 of the shaft e. A springlever e5, pivot-ally mounted on the said arm e2 and engaging at one end the pin e3, is so placed that its other end is pressed against the forward end of the slide-rod]c3 by the spring e4, so that whenthe said slide-rod isA forced forward or outward by the downward movement of the incline f of the leverf the coupling-pin e? will be pressed against the op- '8o erating-bar D by the spring-lever e5, and thus when said pin by the vibration of constantlymoving arm e2 comes into register with the notch d of the said operating-barlsaidypin the said bar with said vibrating arm, and thereby through said operating-bar putting the ruiiier or gatherer into action to'form rufiics or gathers in the work. The are of vertical movement of the rear end of the spring-lever e5 is so short that said lever does not move out of contact with the outer end of the rod f3.

The coupling-lever f is, preferably, actuated by the attendant through a lever f2, engaging the forked inner end of the said lever fand connected by a rod fL with a suitable knee-lever or treadle of ordinary construction located beneath the work-plate A2 of the machine, thus leaving the hands of the attendant free for the convenient manipulation of the work. The ianges f5 at the top and IOO bottom of the incline f serve as stops to limit the movement of the lever f by abutting against the upper and lower sides ofthe sliderod f3.

From the foregoing it will be understood that while the rear end of the lever f2 is held depressed and the coupling-lever j' is tilted' down, so that the parts are in the positions shown in Fig. G and denoted by dotted lines in Fig. l, the coupling-pin e3 will be held in Yengagement with the operating-bar D and the operating-bar D and throwing the rufiier or gatherer out of action. This coupling and upcoupling of the -operating-bar D and its actuating mechanism is easily and instantly effected while the machine is running at any speed and without any appreciable shock or jar, so that gathered or plain sewing at the will of the attendant may be done on highspeed machines without suspending or slackening the running thereof.

We do not claim, broadly, in this application the combination, with a sewing-machine ruining or plaiting attachment provided with an operating-lever, of a vertically-reciprocating bar in the head of the machine and independent ofthe needle-bar and connected with and serving to operate said lever, this feavice for said bar, coupling mechanism for connecting and disconnecting said actuating device and operating-bar, said coupling mechanism comprising a lever having a portion which is inclined relative to the direction of movement of said lever, a sliding rod opera- I ted by the inclined portion of said lever, and

means for holding said sliding rod in contact with said inclined portion: whereby the attendant may throw the said attachment into or out of operation while the machine is running.

2. The combination with a sewing-machine ruffling or gathering attachment, of a notched, operating-bar for said attachment, independent of the needle mechanism of the machine, a constantly-vibrating arm carrying a sliding coupling-pin adapted to engage the notch of said bar, and a lever controlled by the attendant and provided with a portion which is inclined relative to theline of movement of said lever, which latter is connected with the said coupling-pin to control the movements of said pin in coupling and uncoupling said operating-bar and vibrating arm.

3. The combination with a sewing-machine ruiiiing or gathering attachment, of a notched operating-bar D therefor, a constantly-operating vibrating arm carrying a coupling-pin adapted to engage the notch of said bar, a spring-lever carried by said arm and engaging said pin, a slide-rod to operate said lever, and a movable incline, controlled by the attendant, to actuate said slide-rod and throw the said attachment into or out of operation while the machine is running.

1l. The combination with a sewing-machine ruftling or gathering attachment, of an operating-bar therefor, a constantly-moving rockshaft having a vibrating arm provided with a coupling-pin to engage said bar, a lever provided with an incline, a slide-rod controlled by said incline, connections between said slide-rod and coupling-pin, and means whereby said lever may be actuated by the attendant while the machine is running to cause the said coupling-pin to be engaged with or disengaged from said operating-bar.

5. The combination with a sewing-machine ruffling or gathering attachment, of a bar for operating said attachment, an actuating device for said bar, coupling mechanism for connecting and disconnecting said actuating device and operating-bar, said coupling mechanism comprising a lever having an incline, stops for limiting the movement of said lever in either direction, a sliding rod operated by said lever, and means for holding said sliding rod in contact with said incline; whereby the attendant may throw the said attachment into or out of operation while the machine is running, and whereby, also, the movement of the said lever by the attendant, will be limited.

In testimony whereof we affix our signatures in the presence of two witnesses.
